Abstract

A decorative laminated sheet comprises a core (5) consisting of several core paper webs (6) impregnated with phenolic resin, and a covering layer (7) consisting of a decorative paper web impregnated with melamine resin. The core paper webs (6) of the core (5) consist of bleached core paper dyed with inorganic white pigments. The phenolic resin of the core paper webs (6) contains an agent which confers protection against light. The core (5) exposed at the cut edges (8) is just as white as the covering layer (7).

Description

Die Erfindung betrifft eine dekorative Schichtpreßstoffplatte, bestehend aus einem Kern, der von mehreren mit Phenolharz getränkten Kernpapierbahnen gebildet wird, und einer Deckschicht, die von einer mit Melaminharz getränkten Dekorpapierbahn gebildet wird.The invention relates to a decorative laminated sheet consisting of a core which is formed by a plurality of core paper webs impregnated with phenolic resin, and a cover layer which is formed by a decorative paper web impregnated with melamine resin.

Dekorative Schichtpreßstoffplatten (HPL) nach DIN 16 921 weisen einen Kern auf, der üblicherweise aus mit Phenolharz getränkten, ungebleichten Natron-Kraftpapierbögen besteht, die die Kernpapierbahnen bilden. Die Dekorpapierbahn der Deckschicht ist mit Melaminharz bezw. Aminoplastharzen geträntit. Bei der Herstellung wird der aus diesen Papierbahnen bestehende Stapel unter Hitzeeinwirkung zu der Schichtpreßstoffplatte verpreßt (DE-A-1 569 995, GB-A-1 obg 203).Decorative laminated sheets (HPL) according to DIN 16 921 have a core, which usually consists of unbleached sodium bleached kraft paper sheets soaked in phenolic resin, which form the core paper webs. The decorative paper web of the top layer is covered with melamine resin. Aminoplast resins with a tear. During manufacture, the stack consisting of these paper webs is pressed under heat to form the laminate (DE-A-1 569 995, GB-A-1 obg 203).

Nach dem Verpressen und Aushärten erscheinen die Melaminharze der pigmentierten oder unpigmentierten Dekorpapierbahn transparent bzw. farblos. Der Kern der Schichtpreßstoffplatte zeigt jedoch eine braune bis braunschwarze Färbung, die hauptsächlich durch die Eigenfarbe des ungebleichten Kraftpapiers der Kernpapierbahnen verursacht wird, die durch die gelbliche Färbung des Phenolharzes noch verstärkt wird. Dadurch ergibt sich das typische Erscheinungsbild einer dekorativen Schichtpreßstoffplatte: Während die Oberfläche die Farbe der Dekorpapierbahn zeigt, tritt an der Schnittkante eine dunke Linie auf, der besonders auffällig ist, wenn die Oberfläche der Deckschicht hell oder weiß ist.After pressing and curing, the melamine resins of the pigmented or unpigmented decorative paper web appear transparent or colorless. The core of the laminate, however, shows a brown to brown-black color, which is mainly caused by the inherent color of the unbleached kraft paper of the core paper webs, which is caused by the yellowish Coloring of the phenolic resin is intensified. This gives the typical appearance of a decorative laminate: While the surface shows the color of the decorative paper web, a dark line appears at the cut edge, which is particularly noticeable when the surface of the cover layer is light or white.

Bei manchen Anwendungsgebieten im Möbelbau wird diese dunkle Linie an der Schnittkante der Strichpreßstoffplatte ästhetisch als störend empfunden. In vielen Anwendungsfällen werden Schichtpreßstoffplatten als Deckplatten auf Kernplatten beispielsweise Spanplatten, aufgeklebt, um Möbelw'ände, Tischplatten, Arbeitsplatten und dgl. zu bilden. An der Plattenkante liegt dann die die dunkle Linie aufweisende Schnittkiante frei. Diese dunkle Linie ist zum einen störend; zum anderen führt insbesondere bei hoher Wärmeeinstrahlung, beispielsweise bei Sonneneinstrahlung, die dunkle Färbung des Kerns im Schnittbereich zu einer höheren Erwärmung als in der hellen oder weißen Dekorpapierbahn, was wiederum zu unterschiedlichen Wärmedehnungen führt. Diese an sich geringen Unterschiede der Wärmedehnungen können jedoch das Ablösen der Kante der Schichtpreßstoffplatte von der darunterliegenden Fläche begünstigen.In some areas of application in furniture construction, this dark line at the cut edge of the molded board is aesthetically perceived as disturbing. In many applications, laminated sheets are glued on top of core boards, for example chipboard, to form furniture walls, table tops, worktops and the like. The cut edge with the dark line is then exposed at the plate edge. On the one hand, this dark line is annoying; on the other hand, especially in the case of high heat radiation, for example in the case of sun radiation, the dark coloring of the core in the cutting area leads to higher heating than in the light or white decorative paper web, which in turn leads to different thermal expansions. These small differences in the thermal expansions, however, can favor the detachment of the edge of the laminate from the underlying surface.

Es ist zwar bekannt, eine Schichtpreßstoffplatte mit einem auch in der Schnittfläche weißen Kern auszuführen. Hierbei sind die den Kern bildenden Kernpapierbahnen aber mit weißem Melaminharz getränkt. Diese Schichtpreßstoffplatten sind nicht für das sog. Postforming-Verfahren geeignet, bei dem eine nachträgliche Verformung der bereits ausgehärteten Schichtpreßstoffplatte erfolgt, um beispielsweise abgerundete Möbelteile zu bilden.It is known to design a laminate with a core that is also white in the cut surface. Here, the core paper webs forming the core are soaked with white melamine resin. These laminated sheets are not suitable for the so-called postforming process, in which a subsequent deformation of the already hardened Laminate is made to form rounded furniture parts, for example.

Aufgabe der Erfindung ist es daher, eine Schichtpreßstoffplatte der eingangs genannten Gattung unter Beibehaltung der Eignung für das Postforming-Verfahren so auszubilden, daß eine dunkle Linie an der Schnittkante vermieden wird, ohne daß hierfür eine gesonderte Maßnahme zur Abdeckung ergriffen werden müßte.The object of the invention is therefore to design a laminated sheet of the type mentioned at the outset while maintaining its suitability for the postforming process in such a way that a dark line at the cut edge is avoided without having to take a special measure for covering.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kernpapierbahnen des Kerns aus gebleichtem, mit anorganischen Weißpigmenten eingefärbtem Kernpapier bestehen.This object is achieved in that the core paper webs of the core consist of bleached core paper colored with inorganic white pigments.

Der an der Schnittkante sichtbare Kern der Schichtpreßstoffplatte ist hierbei ebenso hell bzw. weiß wie die Oberfläche der Dekorpapierbahn. Er fällt deshalb nicht störend auf und hat auch dieselbe, geringe Wärmedehnung wie die Deckschicht. Die Schichtpreßstoffplatte kann im Postforming-Verfahren nachträglich verformt werden, beispielsweise zur Bildung einer abgerundeten Kante an einer Arbeitsplatte.The core of the laminate, which is visible at the cut edge, is just as light or white as the surface of the decorative paper web. It is therefore not distracting and has the same low thermal expansion as the top layer. The laminate can be subsequently shaped using the postforming process, for example to form a rounded edge on a worktop.

Gemäß einer bevorzugten Ausführungsform des Erfindungsgedankens ist vorgesehen, daß das Phenolharz der Kernpapierbahn ein Lichtschutzmittel enthält. Dadurch wird einer nachträglichen Dunkelfärbung unter Lichteinfluß weitestgehend vorgebeugt.According to a preferred embodiment of the inventive concept, it is provided that the phenolic resin of the core paper web contains a light stabilizer. Subsequent darkening under the influence of light is thereby largely prevented.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung näher erläutert, das in der Zeichnung dargestellt ist. Es zeigt:

  • Fig. 1 einen Querschnitt durch eine Arbeitsplatte oder ein anderes Möbelteil und
  • Fig. 2 einen Querschnitt durch eine im Postforming-Verfahren hergestellte Arbeitsplatte mit abgerundeter Kante.
An exemplary embodiment of the invention is illustrated below, which is shown in the drawing. It shows:
  • Fig. 1 shows a cross section through a countertop or other furniture part and
  • Fig. 2 shows a cross section through a worktop made in the postforming process with a rounded edge.

Auf eine Kernplatte 1, die beispielsweise eine Holzspanplatte ist, ist gemäß Fig. 1 eine dekorative Schichtpreßstoffplatte 2 aufgeleimt. Die Vorderkante der Kernplatte trägt ebenfalls einen aufgeleimten Streifen 3 aus einer dekorativen Schichtpreßstoffplatte, die in gleicher Weise aufgebaut ist wie die Schichtpreßstoffplatte 2. An der Unterseite der Kernplatte 2 ist eine nur schematisch angedeutete untere Deckplatte 4 angeklebt.1, a decorative laminate 2 is glued onto a core board 1, which is, for example, a chipboard. The front edge of the core plate also carries a glued strip 3 made of a decorative laminate, which is constructed in the same way as the laminate 2. A lower cover plate 4, only indicated schematically, is glued to the underside of the core plate 2.

Die Schichtpreßstoffplatte 2 besteht aus einem Kern 5, aus mehreren Kernpapierbahnen 6, die mit Phenolharz getränkt sind. An der Oberseite der Schichtpreßstoffplatte 2 befindet sich eine Deckschicht 7, die aus einer beispielsweise weiß pigmentierten Dekorpapierbahn besteht, die mit Melaminharz getränkt ist. Die Kernpapierbahnen 6 und die Dekorpapierbahn 7 sind miteinander unter Hitzeeinwirkung verpreßt und ausgehärtet, um die dekorative Schichtpreßstoffplatte 2 zu bilden.The laminate 2 consists of a core 5, of several core paper webs 6, which are impregnated with phenolic resin. At the top of the laminate 2 there is a cover layer 7, which consists of, for example, white pigmented decorative paper web, which is impregnated with melamine resin. The core paper webs 6 and the decorative paper web 7 are pressed together under the action of heat and cured to form the decorative laminate 2.

Die Kernpapierbahnen 6 des Kerns 5 bestehen aus gebleichtem Kernpapier, das mit anorganischen Weißpigmenten eingefärbt ist. Das Phenolharz, mit dem die Kernpapierbahnen 6 getränkt sind, ist durch Zusatz von Lichtschutzmitteln modifiziert. Bei dem dargestellten Ausführungsbeispiel wird für die Kernpapierbahnen 6 ein Spezialpapier mit etwa 140 g/cm² Flächengewicht eingesetzt.The core paper webs 6 of the core 5 consist of bleached core paper which is colored with inorganic white pigments. The phenolic resin with which the core paper webs 6 are impregnated is modified by the addition of light stabilizers. In the illustrated embodiment, a special paper with about 140 g / cm² basis weight is used for the core paper webs 6.

An der Schnittkante 8 der Schichtpreßstoffplatte 2 liegt der Kern 5 in einem Streifen 9 frei. Dieser Streifen 9 ist ebenso hell bzw. weiß wie die Deckschicht 7 der Schichtpreßstoffplatte 2 und wie die Oberfläche des Kantenstreifens 3.At the cutting edge 8 of the laminate 2, the core 5 is exposed in a strip 9. This strip 9 is as bright or white as the cover layer 7 of the laminate 2 and like the surface of the edge strip 3.

Die in Fig. 2 dargestellte Arbeitsplatte ist im Postforming-Verfahren hergestellt. Die Schichtpreßstoffplatte 2 ist nach ihrer Herstellung zur Bildung einer abgerundeten Kante verformt worden. Gleiche Teile sind mit gleichen Bezugszeichen wie in Fig. 1 bezeichnet.The worktop shown in Fig. 2 is made in the postforming process. The laminated sheet 2 has been deformed after its manufacture to form a rounded edge. The same parts are designated with the same reference numerals as in Fig. 1.
